l- EXHAUST EMISSION CONTROL COMPOSITION BACKGROUND OF THE INVENTION Thisinvention relates to a composition which minimizes the emissionofexhaust irritants into the atmosphere. More particularly, this inventionrelates to an aqueous solution of borax and baking soda for use withautomobiles.

Air pollution and the lack of clean air is now one of the pressingproblems of this age. The great amount of impurities which is beingpoured daily into the air by exhaust gases of industrial processes orfrom the many automobiles now in use throughout the world isslowly'poisoning people, thus impairing their ability to lead healthyand long lives. This problem is particularly acute in the cities wherethe population is dense. Various solutions have been proposed'to solvethis problem with respect to exhaust gas from automobiles. For example,it has been suggested to reburn the gas, thus avoiding the formation ofcarbon monoxide, a poisonou's'product. Another solution is the use of adevice such as'that described in U.S. Pat. No. 3,353,336 which spraysthe exhaust gas with anaqueous solution of sodium lauryl sulfate, borax,chlorophyl A and trisodium phosphate. However, this composition is noteasily vaporizable due to the soap which after contacting the gas leavesa residue that must be removed from the combustion engine.

SUMMARY OF THE INVENTION Accordingly, it is an object of thi s'inventionto provide a composition which will minimize theernission of irritantsfrom an exhaust stream of a combustion engine.

Another object of the invention is to provide a composition which easilyvaporizes within a combustion engine.

These and other objects will become apparent as the descriptionproceeds.

DESCRIPTION-OF THE PREFERRED EMBODIMENTS believed that the beneficialresults obtained by the invention take place as follows: Theborate-bicarbonate solution vaporizes into a steam when it comes intocontact with the hot manifold or heated exhaust gas, and the steam actsto cleanse the exhaust gas by removing some of the carbon and carbonproducts before the gas is emitted into the air. The principle by-whichthe irritants in the gas are'minimized is not fully understood and mostlikely consists of acleaning and absorption process. However, it is notintended that this invention be limited to any specific theory ofoperation.

The amounts of soda, borax, and water to be used in accordance with theinvention is not limited to that previously described in the preferredembodiment but can be any amounts which reflect approximately the sameratio; namely, 1 pound: l pound: 15 gallons. The amount of solutioninjected into the manifold will depend on the horsepower of the motor;however, it should not exceed the amount of gasoline consumed by themotor. Although the invention is described only with reference to asingle manifold, it is equally operable with two and, therefore, isapplicable to cars having dual exhaust systems. I

it will be understood by those skilled in the art that variousmodifications can be made of this invention without departing from thescope of the invention.

We claim:

1. An aqueous composition for minimizing the emission of irritants intothe atmosphere in combustion engine exhaust which consists of Na.,B O-,and NaHCO;,.

2. A composition according to'claim l in which the Na B,O NaHCO andwater are present in approximately a l pound: 1 pound: 15 gallon ratio.

3. A method for minimizing the emission of irritants from an exhaustsystem of a combustion engine which comprises the steps of:

a. forming an aqueous solution of Na..B O and NaHCO and b. injectingsaid solution into the exhaust manifold as said engine is running sothat saidsolution vaporizes when it comes into contact with the heatedmanifold and the heated gas and forms a steam. which acts to clean saidexhaust gas.
